How is the flour sifter used in the flour production process?

The production process of Wheat flour sifter:

The processing accuracy of flour is mainly measured by the bran star content of flour. The whiter the pink, the less bran star content, and the higher the accuracy of flour. The processing accuracy of flour is affected by many factors such as raw grain, processing technology and operation indicators. Therefore, higher requirements are put forward for the screening of wheat and the screening accuracy of flour particle size. After the wheat has been milled, it needs to be selected using a flour sifter. Mainly in the milling process, in order to improve the flour yield, the endosperm on the cortex must be scraped as much as possible, and a part of the aleurone layer will be scraped off and mixed into the flour in the process again.

In the process of scraping and peeling, a small amount of wheat husk is also broken into fine powder, which needs to be sieved into the flour to improve the particle uniformity of the flour. In this production process, it needs to be screened by a flour sieving machine to improve the fineness of the flour. In addition, the cleaning of wheat is the basic work of milling. Only when pure wheat is sent to the milling workshop for processing can high-precision flour be produced. It is necessary to use a sieving machine to clean up various impurities contained in wheat to reduce the impact of impurities on the fineness of flour. Only by increasing the heterochromatic impurities can the black spots in the flour be reduced and the accuracy of the flour be improved.
